v To all whom tt may concern:

Be it known that we, LAVINAS B. HAMIL- TON and GnAJeLEs F. HARLOW, both of Boston, in the county of Suffolk and State of Mes.

and, useful improvements in that class of clipping or shearing machines operated by'the alternate pressure and'release'of air. A portion of these improvements is, however, applicable to machines operated by any other method.

. The-object of these improvements is mainly to provide a simple, economical, and effective method of vibrating the cutter or cutters of a clipping or shearing machine, and to so hold the support ofa vibrating cutter as to allow it to be readily released to admit the turning of the cutter to carry any broken or injured tooth to the rear, to prevent its interference with the operation of the remaining perfect teeth; and to effect these ends, our invention consists mainly in a hollow metallic or other suitable handle, divided at its rear portion into two airtight chambers by a central flexible partition or diaphragm, operated by the alternate admission and withdrawal, through tubes opening'into .said chambers, of air, so as to vibrate laterally a lever connected with the said diaphragm and actuate a cutter,in the desired manner, as will be hereinafter more fully explained. These improvements also con s'ist-in a split sleeve or clamp, arranged to support, so as to allow the turning of, a standard or socket, and to be readily adjusted to the stem-ofa cutter-support, to hold the same in position, or to be readily released therefrom, to allow the turning of the cutter to carry to the rear any injured or broken tooth, as will be duly explained.

In the drawings, A represents a hollow metallic orother suitablehaudleof a clipping or shearing machine.' This handle is at the rear of greater depth than the 'front, toward which it tapers in. the-curved forin shown, or is 0th; erwise shaped, to be conveniently held. in the hand of the operator, and is formed at the 'front end with an upward and forward projectiug'arm,'A, formed at the extremity with a' screw-socket, A, which receives and allows the turning of a vertical screw-stem, B, that connects at the bottom with (so as to hold).a metal disk or cutter, G, countersunk onits'to p, and formed around its edge with teeth a, beveled upward from their point to the point, and

*'extending inward to'the heel, of npper teeth,

b,-formed around and beveled upward from the edge of an upper metal disk or'cutter, l),

' which is countersunk on the top and bottom;

orthe cutters may be otherwise 'formedand arranged, screwed or'otherwise attached, so

as to be readily released. E'is a metal circular plate or cutter-supportQformed with an upright screw-socket stem, B, which is provided, I

between the. sockets A" and E, with a spiral spring, 0, that bears upon thestem B, to hold downthe cutter D properly in place. The top of the stem B is provided with a screw-nut, B,

that bears uponthe topof, the socket A, and

regulates the stem B, so as to tighten or loosen thelower-cutterO from the upper cutter D Surrounding the lower portion-of the socket stem E, above the'top of the disk or plate E,

is a split sleeve or cylindrical clamp, F, divided vertically on one' side, and formed-with screwears d 41, provided with a screw, for the purpose of tightening or loosening the clamplg" to hold the stem E, or to allow its release tofree the cutter-support E, so as to permit the turning and adjusting of the .cutter D to carry back any injured tooth and prevent its interference with the operation of the perfect teeth. The clamp F is formed on its inner side with a bottom annular lug, f, that receives and holds .the .end of a stem, g,on which turnsan up'- right cylindrical standard or socket, H, that has a seat on the top'of the lugf, and is formed with an inner extending arm, h, having'an end socket that receives and allows the lateral playof the outer end of a lever, I, which extends withinnearly to the end of the handle A, passing through or connecting with, so as to be turned by,'a'pivot, 'J, that is located a snitable distance from the forward end, and extends vertically through, so as to turn in, the handle A." The lever I is slotted orbifurcated, or 0thor diaphragm, K, which extends longitudinally asfar as the pivotJ through the center of the rear portion of the handle A, dividing the latter into two air-tight chambers, L L. One side of the rear portion of the handle A forms the pivot J, in a separate piece from the other side, and each side, at the top, bottom, and rear, is formed with cars it" 6, provided with screws, for holding or releasing the two sides, between which the edges vof the partition or diaphragm K extend and are securely held. The sides" of the handle, near the pivot J, are 'held or released by screws j, or otherwise, that extend through the edges of the partition K;

and sides of the handle, the interior of which sides is formed with screw-sockets to receive.-

the screws. At the rear, omeither side of the partition or diaphragm K, between it and the bifurcated interior sides of the lever I, is a thin tin or other suitable washer or plate, m m, heldbyaserew or-screws extending through the lever, or otherwise secured, The washers are curved in the shape shown by thedotted lines, Fig. 1, or otherwise formed and arranged,'

for the purpose of stiffening the partition, and eflectually producing the desired action to' the lever. The rear portion of the handle A is formed or provided on either side with tubes M M, 'thatmay be connected with any apparatus, or device, or arrangement of devices for admitting and withdrawing air alternately through the tubes into and from the handle on either side of the'partition or diaphragm.

The operation of our invention is as follows: The tubes MM being connected-with any suitable apparatus or device, &c., for; supplying and withdrawing air to and from the handle, as above mentioned, the air is first admitted- 'in one of the chambers L or L and withdrawn from the other, and vice versa. This action rapidly performed causes the diaphragm or partition K to berapidly vibrated laterally,

Lset' forth. I 4:. In combination with a vibrating lever of a clipping or shearing machine, a socket-stem,

thereby carrying to and fro laterally the lever- I, which; engaging inthe arm 11. of the socket H, carries 'the latter and the. clamp F, counected by the stem-g, with it, and holding the I stein E of the cutter-support E,thus vibratingthe cutter D to and fro laterally over the stationary under cutter G, and producing the desired clipping or'shearing movement.

In case of accident to any of the forward teeth of, the cutter D, by unscrewing the clamp F the hold on the socket E is released, and the cutter permitted to be readily turned to carry the injured tooth or teeth tothe rear,

out of the way of interfering with the opera. tion of the perfect teeth. I y

Having thus described o"-r iinprovements, what we claim as our invention, and desire to have secured to us by Letters Patent, is-- 1. A cylindrical clamp or split sleeve, F,

formed with screw-ears d (F, held together or I released by a screw, in combination with the socket-stem of a cutter-support, E,*and cutters G and D, substantially as and for the purpose described. a

2. In a clipping-machine, the combination of the hollow'handle A, diaphragm K, and

vibrating lever I, the latter being actuated by I compressed air or steam, and actuating the cutting mechanism, substantially as described,

. for the purpose specified;

3. In combination with the handle A, tubes M M,-flexible partition or diaphragm K, and

lever I, the washers m on, all arranged and operating substantially as and for the purpose H, having socket-arm h, stem g, adjustable split sleeve or clamp F, having lug f, stem E of cutter-support E, cutters 0 D, stem B, and handle-socket A, all arranged and operating substantially as specified.

In testimony'whereof .we have signed our names to this specification in the presence of two subscribing witnesses.
